STUD-RETAINING MEAns.

inaaaiv.

To all whom it may concern:

Be it known that I, QIARLES W; gronsnn, a citizen of the United St-ates, residing at Hartford, in'the county of Hartford and State of Connecticut, have invented, certain new and useful Improvements in Stud-Retaining Means, of specification. 1.

This invention relates to what I shall for convenience term stud retaining means.

which the following is a Stud-retaining means involving the invention can be employed with advantage in many different connections, it being especlally useful, however, in fields where the part withwhich it is associated is subjected fectivelv held in position and against rotary and axial movements.

In the drawings accompanying and forming part of the present specification I have shown in detail a convenient form of embodiment' of the invention which I will set forth fully in the following description to enable those skilled in the art to practise the invention. I am not limited, however, to this particular disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a side elevation ofauniversaljoint equipped with stud-retaining means involving'the invention, the casing of the joint being in section. j

Flg. 2 1s a detail v1ew partly in elevation and partly in sectlon of thecruciform coupling-member of the joint, several bearings appearing, and associated with the same is stud-retaining means involving the invention.

, cruciform member to which I have already alluded.

Like characters referto like parts throughout the several views, which are on different scales.

In Fig. 1 I have shown the malnmembers 2 and 3 and llllGCIllClfOIIIl coupling airfiaia member 4 of auniversal'joint which presents constitute a feature, in that the stud-securing means involving the invention act, as a highly advantageous medium for pivotally uniting the cruciform couplmg-member 4 with the main members 2 and?) of the joint.

These main members 2and 3 mayasshown b forked, each fork comprising branches as a in itselfv nopart ofthe present invention, although as to one aspect thereof, ltClOBS 5. The branches 5 of the forks are as illus- 1 trated separate from but suitably connected with the respective main members 2 and 3. As will be clear, the fork of the member 2 is transverse or at right angles to thefork of the member 3 as common in universaljoints. The couplingmember 4t as will be understood is pivoted between the pairs of,

.so and 3, by reason of which the latter are per mitted "to relatively move. universally. I

bearings 5 of the respective main members 2 again wish to make clear that the stud-retaining Ior securing means whilehighly ad vantageous when lncorporated 1n a un1- versal-joint such as thatbriefiy olescribed,is capable of use in many other arts and especially in association with parts which are subjected to strains and stresses which ordinarily would tend to dislodge a pivot;

.I will describe in detail merely one stud and its associated elements for pivotallyl connecting the cruciform coupling member or its equivalent to a bearmg as 5 or analogous part, 1t being clear that thls descrip tion applies to the other three studs and; In a universal.

their associated elements. joint, although it is not always necessary, I prefer to provide four of these studs such as 6. Thecoupling member has a cylindrical opening as which as shownis of two diameters, the portion of larger diameter being in register with a cylindrical, or circular openingas 8 in the appropriatebearingfi as best shown in Fig. 2. The cylindrical hollow stud 6 it will be noted, extends en tirely throughfthe bearing opening 5 and partially into but does not bottom in the portion of larger diameter of the cylindrical opening 7. In the construction shown the portion of larger diameter of the opening 1 or bore 7 receives'the disk 9 which as will be understood fits against the bottom of the larger portion of said bore 7. Said larger part of the bore has an undercut groove or common axes of the openings or bores 7 and 8. dis will be understood the bottom of the large part pf the bore 7 presents the bottom of the undercut groove or channel .10. This disk,9 as shown is provided on its outer side with. a. projection 11 which as shown may be practically-rectangular and which is eccentric to. thedisk9, although this may not always. .be necessary. It is desirable, ifnot essential, however, that the opening 12 in the projection. 11 should be eccentric to the disk, being in the 1 organization shown back of the center oron the side thereof opposite to the marginal Kportion of the disk which enters the groove or channellO. The vital consideration, therefore, is preferably that therhole or opening 12, thewallof which as shown is, threaded, should be eccentric of the disk; ,The purpose ofthe tapped hole or opening .12 ,willbe hereinafter explained,

and Imight observe that the hole preferably extends to the'bottom of the disk. The projection 11 in addition to receiving the threaded portion of a pin or equivalent mem ber asawill hereinafter particularly appear is interlocked with the ,hollowstud, and this isobtained by interlocking the disk and stud for. instance by fitting the projection 11 in a channel 13 in the under side of the stud or [hollow pin 6,: the projection 11 constituting a suitable key and the stiidrh'aving a seat to receivezthe key which asgmaybe inferred is a simple waylof securing 'the desired condition,, Extending through the hollow stud Jor pivotlfi is ascrew 14, the inner end of which is tapered or 'ofifrusto-co'nical form to insurefits' easy application. This screw 14 hasahead .l6 'to fit: in the counterb'ore 17 in alsoseated in the slot 22in the headf16. Ob-

viously the cotter, pin-20 presents a convenient way of'holding the screw 14 in assembled'relation with the hollow stud 6. v

I will describe how one hollow stud'a's 6 "when the hollow stud 6 is passed through the opening 8 and its inner or forward end interlocked with the "disk by seating the projection 11 into the groovev or channel 13. The screw 14 isv now passed through the stud 6 until its threads 18 meet the threads of the hole or opening 12 when the screw 14 is turned to connect it, with the disk 9. When this is accomplished the cotter pin 20 is introduced, and when it is positioned, the parts will all be in correct relation and the hollow stud 6 will be eifectually'and positivelyheld against turning and axial move ments. l p

Ina universal joint it is customary to provide for proper lubrication by incasing the main members 2 and 3, and for this purpose a casing such as 23 nay be provided. This casing as may be inferrediorms no part oi the present invention, and I speak of it briefly merely because it is shown.

It might be noted that the disk 9 acts as a convenient nut, and I might also state that the cotter pin 20 provides a suitable way of uniting the stud 6 and screw 14 together.

I desire also to call attention to another important matter, that is the fact that the peripheral or marginal portion of the disk 9 by extending into the undercutlO effectually prevents turning movement of the disk as well as movement thereof in the direction of the axis of the screw 14. The tapped hole 12 is eccentric to the disk 9 to an extent approximately equal to the maximum depth of the channel or groove 10, the consequence beingwhen the disk bottoms in thechannel or groove, the axis of the tapped hole will be coincident with the axes of the bores 7- and 8.

What I claim is:

1. The combination of a hollow stud, a screw extending through and removably connected with said stud, and a nut with which the screw is connected, interlocked with the stud and having means associated with it to prevent turning movement and also movement in thedirection of the axis of the. screw.

2. The combination of a hollow stud, a screw extending through and removably connected with the stud, a nut with -which the screw is connected, interlocked with' the stud, and two elements connected pivotally by the stud and one of them being provided with means to prevent turning movement of the nut and also movement of the nut in the direction of the axis of'the screw.

3. The combination of a hollow stud, a

screw extending through the stud and removably connected therewith, a nut with which the screw is connected, interlocked with the stud, and two bored elements, the bores of which register to receive the stud, one of the bores having a groove and the nut having a portion extending into the groove.

4. The combination of a hollow stud, a screw extending through the stud, a pin removably connecting the screw and the stud, and a nut with which the screw is connected, said nut being interlocked with the stud and having'means connected with it to prevent the same from accidentally turning and also from moving in the direction of the axis of the screw.

5. The combination of a bored element, a nut fitted in the'bore of the element and interlocked with said element, a screw in threaded connection with the nut, a hollow stud through which the screw passes, a second bored element through the bore of which the stud extends, the stud extending into the other bore, and a pin for removably connecting the screw with the stud.

6. The combination of an element having a bore, a nut fitted in the bore element, said element being undercut, and the nut extending into the undercut portion, a second bored part, a hollow stud extending through the bore of the second bored part and into the first bore and interlocked with the nut, and a screw extending through the stud and nut, in threaded engagement with the nut, the screw being pinned to the stud and extending into the first bore.

7. The combination of a hollow stud, a screw extending through the stud and removably connected therewith, a nut with which the screw is connected, the nut having a projection and the stud having a groove to receive the projection, the nut also having means associated therewith to prevent 1ts movement in the direction of the axis of the screw and also to prevent its accidental turning.

8. The combination of a hollow stud, a

screw extending through the stud, and a nut with which the screw is connected interlocked with the stud and having means associated with it to prevent turning movement and also movement in the direction of the axis of the screw.

9. The combination of a part having a cylindrical bore, a nut supported by a wall of the bore, the nut having an eccentric tapped holeand the bore having an undercut groove to receive a peripheral portion of the nut, and the axis of the tapped hole when said periphery is seated in said groove being concentric with the axis of the bore,

a second bored part, a bushing extending through the bore of the second bored part and into the other bore and also interlocked with the nut, and a screw extending through the bushing and in threaded engagement with the nut.

In testimony whereof I affix my signature in the presence of two witnesses.
